C++实现数组元素逆置

#include <iostream>
using namespace std;
 
int main(){
    // 定义数组
    int arr[5] = {1,2,3,4,5}; 
    int start = 0;
    int end = sizeof(arr) / sizeof(arr[0]) - 1;   
    cout << "逆置前的数组：" << endl;
    for(int i = 0; i <= end; i++){
        cout << arr[i] << "  " ;
    }
    cout << endl;
    
    //逆置
    while(start < end){
        int temp = arr[start];
        arr[start] = arr[end];
        arr[end] = temp;
        start++;
        end--;
    }
    
    //逆置后数组
    cout << "逆置后的数组：" << endl;
    for(int i = 0; i <= sizeof(arr) / sizeof(arr[0]) - 1; i++){
        cout << arr[i] << "  " ;
    }
    cout << endl;
 
    return 0;
}
